Quick answer

  • Combined support often reaches EUR10,000-EUR20,000+ on common retrofit paths.

What grants are available in Ireland?

SEAI is the main grant provider for home energy upgrades, and support is usually spread across different upgrade types rather than one single payment.

Most homeowners combine multiple home energy upgrades based on their home, upgrade path, and expected overall savings.

  • Insulation grants
  • Heat pump grants
  • Solar PV grants
  • Windows and doors grants (limited or conditional)

Grants by upgrade type

Heat pump grants

Typical support is often around EUR6,500, while heat pump cost in Ireland still depends on eligibility and scheme rules.

Who is eligible for retrofit grants?

  • Owner-occupied homes are typically eligible for many grant types.
  • Some landlords may be eligible depending on the scheme.
  • A BER assessment is often needed where minimum BER improvement is required, especially for heat pump routes.
  • Technical requirements still need to be met before support is approved.

How the grant process works

  1. Assess your home (BER and technical readiness), often starting with a BER assessment.
  2. Choose upgrades in a practical order using a retrofit plan and what to upgrade first approach.
  3. Apply through SEAI and/or your contractor route.
  4. Complete the upgrade works.
  5. Grant support is paid after completion.

Important: grants usually come after the work is completed, so upfront budget is still needed.

Common mistakes with grants

  • Choosing upgrades based only on grant size.
  • Installing a heat pump before improving insulation.
  • Underestimating additional costs not covered by grants.
  • Assuming grants cover the full project cost.
  • Not planning upgrades in the right order.

How grants fit into your upgrade plan

Grants work best when they follow a fabric-first approach, so your home is prepared before bigger system changes.

A practical sequence is usually insulation, then ventilation, then heating, then solar.

For sequencing guidance, read what to upgrade first. For budget planning, compare the cost after grants. You can also consider whether the right sequence may increase house value.
